Smooth muscles constrict veins when blood pressure suddenly drops. These types of muscles are the non striated, involuntary muscles found in blood vessels, veins, arteries, the uterus, the bladder, and reproductive tracts.
Thee difference between muscle in veins and arteries is that muscles of arteries are thicker compared to those of veins.
They are involuntary muscles.

His face was red and striated with fine veins.
the three blood vessels are the Veins capillaries Arteries the arteries.
Arteries drain (pump blood) into veins. Veins drain into your lungs and heart to be re-oxygenated. (This is not true for veins and arteries to and from your lungs.)
Veins do not pulsate Arteries pulsate Veins can easily collapse Arteries do not collapse (except in shock) Veins contain valves Blood pressure is low in the veins and higher in the arteries
Cellulose is what surronds veins and arteries.
